Abstract: Objective To understand the relationship between embryonic chromosomal abnormalities and missed abortion by high-throughput gene sequencing, so as to provide a basis for guiding the next pregnancy.Meth-ods By chromosome detection on villi chromosome of 52 cases of missed abortion by high-throughput gene sequen-cing technique, the types of chromosome abnormalities and the proportion were investigated.Results Among villi samples from the 52 cases of missed abortion, chromosomal abnormalities were founded in 28 cases, including 24 ca-ses of number abnormality (17 cases of trisomy, 6 cases of triploid and a case of monomer) and 4 cases of structural abnormalities.Conclusion Embryonic chromosomal abnormality is the main cause of missed abortion in early preg-nancy.High-throughput gene sequencing technology used to detect the villi chromosome is comprehensive, fast and accurate, helping to clarify the cause of missed abortion and guide the next pregnancy reasonably.
